Reading binary data from an image

sample code:

string path = “C:\\img1.jpg”;

FileStream fs = File.Open(path, FileMode.Open, FileAccess.Read);

byte[] b = new byte[fs.Length];

fs.Read(b, 0, b.Length);

fs.Close();

Converting the binary data from Bytes to String

sample code:

string str = Convert.ToBase64String(b);

Converting the String back to an Image 

sample code:

MemoryStream ms = new MemoryStream();

Image img11;

byte[] b1;

b1 = Convert.FromBase64String(str);

ms = new System.IO.MemoryStream(b1);

img11 = System.Drawing.Image.FromStream(ms);
